Abstract
To provide a method for cost reduction of sea water desalination.SOLUTION: In water preparation by a sea water desalination method, an evaporation method requires electric energy as a pump power, a reverse osmotic method requires electric energy for pressure application and fluid transfer pump, and moreover, an electroosmosis method requires electric energy for dialysis and pump power; by using photovoltaic generation for these electric energy, sea water desalination cost and water preparation cost are reduced.SELECTED DRAWING: None
Description
本発明は、太陽光発電を使用して、海水淡水化のコストを削減する。The present invention uses solar power to reduce the cost of seawater desalination.
海水淡水化のコストが高い。The cost of seawater desalination is high.
海水淡水化のコストを削減する。Reduce the cost of seawater desalination.
海水淡水化方式による水の作製において、必要な電気エネルギーに、引用文献、特願２０１９－６１８１３の太陽光発電を使用します。
発電効率が３倍に上昇した太陽光発電を海水淡水化方式に利用します。蒸発法は、原水の加熱に熱エネルギーが必要で、ポンプ動力として電気エネルギーが必要です。逆浸透法は、加圧および流体輸送用ポンプに電気エネルギーが必要です。電気浸透法は、透析及びポンプ動力用として電気エネルギーが必要です。こうした電気エネルギーに太陽光発電を使用します。海水淡水化コストが削減され、水の作製コストも削減されます。In the preparation of water by the seawater desalination method, the solar power generation of the cited document, Japanese Patent Application No. 2019-61813 is used for the necessary electrical energy.
Photovoltaic power generation with three times the power generation efficiency will be used in the seawater desalination method. The evaporation method requires thermal energy to heat the raw water and electrical energy to power the pump. Reverse osmosis requires electrical energy for pressurization and fluid transfer pumps. Electroosmosis requires electrical energy for dialysis and pump power. Solar power generation is used for such electrical energy. Seawater desalination costs are reduced, and water production costs are also reduced.
水の作製コスト削減により、水を売るビジネスが普及します。
発展途上国など、水不足の地域に、水を供給する支援にも役立ちます。Businesses that sell water will become popular due to the reduction in the cost of producing water.
It is also useful to help supply water to areas with water shortages, such as developing countries.
海水淡水化方式による水の作製において、必要な電気エネルギーに、引用文献、特願２０１９－６１８１３の太陽光発電を使用します。In the production of water by the seawater desalination method, the solar power generation of the cited document, Japanese Patent Application No. 2019-61813 is used for the necessary electrical energy.
